Chemical-physical plants

Biological plants

  • Industrial discharge treatment
  • Treatment of discharges coming from biogas production (digestate treatment)
  • Zootechnical effluent treatment
  • Landfill leachate treatment
  • Groundwater and contaminated site treatment
  • Rain water treatment plants
  • Water recovery and reuse
  • Zero discharge plants
  • Sequential batch reactor plants (SBR)
  • Membrane bioreactor plants (MBR)
  • Nitro-denitro biological plants
Water and wastewater depuration is guaranteed by a whole of technologies and processes that are necessary to eliminate the pollutants.
Simpec constructs two kind of waste water treatment plants: chemical-physical plants and biological plants.

In different situations the two plant solutions, can coexist for the effluent treatment.
Cleaned water can be discharged or, if it's possible, it could be used again in the productive processes with the installation of specific plants (evaporators, osmosis plants, ultrafiltration units, etc.)


Chemical-physical plants

Chemical-physical plants make the pollutants insoluble by the use of chemical products and subsequently they separate the insoluble part (sludge) from the water (physical process).
The main parts of the chemical-physical plants are:
  • Acidification
  • Coagulation
  • Neutralization
  • Flocculation
  • Sedimentation/ decantation
  • Sludge filtration
  • Cleaned water final filtration
If there is presence of pollutants like chrome and cyanide, Simpec installs specific sections for cyanide and chrome reduction.


Biological plants

Biological plants use communities of living organisms (bacterias).
The action and cooperation of different bacterias, eliminates the pollutants contained in to the effluent.
The growth and the development of these bacterias, is due to the organic substance contained into the wastewater.
The main parts of the biological plants are:
  • Nitrification
  • Denitrification
  • Flocculation
  • Sedimentation
  • Sludge filtration
